Good day!

I would like to ask what's wrong with my code in backing up my mysql database. Here's my code:

VB

Process.Start("C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqldump.exe", "-u username -p password db -r """ & txtpath.Text & "\backup.sql"" ")

whenever I use it, I get a 0 MB backup file. Furthermore, the command prompt shows asking for a password. When I entered my password in the database, it stated that there has been an error.

Any help will be appreciated! Thank you and God bless!

Please provide full details of the error you receive, we cannot guess it.

There shouldn't be a space between -p and the actual password

Because you have left a space after the -p you are essentially saying that the database does not have a password ... but it does - which is why the prompt then appears.

It then tries to backup a database called password (or whatever your password is) instead of your actual db - hence a 0 byte file

Hi! I tried your solution, but the error prompted that mysql cannot connect.

you'll need to confirm that you've got the logon id, password and database name correct ... given that you were prompted for the password when you had the space in I would hazard a guess that you've miskeyed the password ... it's probably case-sensitive as well
